4TO ALL WHOM I'l MAY CONGERN:

Be it known that I, JOHN WILDHACK, of Pekin, in the county of Tazewell, and State of Illinois` have invented a new and useful Improvement in Oil Cup for Steam-Engine Cylinders; `and 'Ido hereby declare that the following is a full, oleair, and exact description of the sume, reference being hed to the annexed drawings, making part of this specification,` in which- I Figure 1 is a sidcelevaton; and

Figure 2 is a; vertical central section. y

The seme letters are employed in each figure in the indication of the same parts.

My invention consists in sojfeonstrncting u lubricator for engine cylinders that the handle of the stop-cock shall be itself the oil cup, and atlthe same time in so constructing the stop-cock that the steam can never pass from the'cylinder into'. the lopen air through the lubricator. The following description will enable one skilled in the art to constructny'improved oil cup. 'i

' A is a stem, having? one end insertedby a screw-thread into the cylinder, and the other open and formed with a funnel-formed'oup, A. A bulb is formed at A" with a circuler opening through it on opposite sides, to

receiyethe stop-cock B, the twoTha-ving thc general appearance of Aan ordinary spigot. There is, however, no

openin'g'throngb the stopcock toform a connection between its opposite sides, as in the ordinary case, but a pipe is formed at its opening on one side only, and leading into the chemberC formed in one end of tbe crosshandle. l The opening of this-pipe corresponds with the size and position of the tube' leading through the shank; the other parts of the stop-cock are solid, and the shank is ground to forni a steam-tight joint with the socketin the bulb A". When the chamhercd end of the'handle is turned down, as shown in the drawings, the oil muy be poured through the `month A into the chamber C. rlhe handle being then turned half over, the pipe C is brought into connection with the tube leading into the cylinder through which the oil flows. It is impossible for the steam to blow the bil-out of the cup, for the two ends of the pipe through the stem A cannot be connected.

. Whatl claim as my invention, and desire to secure by Letters Patent', is-

1. An oil cup for the cylinders of steam engines, in which achnmber,`C, in the handle B is made the reservoir for receiving the oil, substantially es set forth. i

2. The ste-ni A and stop-cock B, when so constructed und arranged that the stop-cock shall be the receiver for the oil, and the passage of steam through the stemvbe prevented, substantially in the manner set forth.

3. So combining the -steun A and stop-cock B that the pipe C may be brought alternately into connection with the openings through the stem on each side of the stop-cock, substantially as and for the purpose set forth.

In testimony whercot` I have signed my name to this specileation in the presence of two subscribing witnesses1 JOHN WILDHAOK. l
